The first electronic device 50 and the second electronic device 60 may be different types of electronic devices including portable electronic devices (e.g., notebook computers, tablet PCs, smart phones) or wearable devices (e.g., smart watches). The first electronic device 50 and the second electronic device 60 may also be an electronic device and an accessory thereof, respectively (e.g., a tablet PC and its expanding base, a watch body of a smart watch and its watch belt and so forth), but the invention is not limited to the above.
With aforesaid disposition, in addition to the first charging portion 112, the base 110 of the charger 100 further includes the second charging portion 114, so that one single charger 100 is capable of charging different types of electronic devices or the accessories thereof respectively through the first charging portion 112 and the second charging portion 114. Accordingly, amount of the chargers may be reduced, so that it is convenient in storing or carrying the chargers for the user, and the problem of confusion in using multiple chargers may also be solved.
In the present embodiment, a thickness T1 of the first charging portion 112 is less than a thickness T2 of the second charging portion 114. Accordingly, when the charger 100 is in states as shown in FIG. 2 and FIG. 3, a distance D1 between the first charging portion 112 and the clamping component 120 is greater than a distance D2 between the second charging portion 114 and the clamping component 120, so that the first electronic device 50 with a greater thickness is adapted to be clamped between the first charging portion 112 and the clamping component 120 as shown in FIG. 2, and the second electronic device 60 with a smaller thickness is adapted to be clamped between the second charging portion 114 and the clamping component 120 as shown in FIG. 3.

FIG. 12 is a side view of a charger according to another embodiment of the invention. FIG. 13 is a schematic view illustrates rotation of the base depicted in FIG. 12. FIG. 14 and FIG. 15 are schematic views respectively illustrating the clamping component depicted in FIG. 12 and FIG. 13 being pushed. In a charger 300 illustrated in FIG. 12 to FIG. 15, dispositions and actions regarding a base 310, a first charging portion 312, a second charging portion 314, a first connecting portion 316, a clamping component 320, a first clamping portion 322, a second clamping portion 324 and a second connecting portion 326 are similar to dispositions and actions regarding the base 210, the first charging portion 212, the second charging portion 214, the first connecting portion 216, the clamping component 220, the first clamping portion 222, the second clamping portion 224 and the second connecting portion 226 as shown in FIG. 6 to FIG. 11, thus related description is omitted hereinafter.
A difference between the charger 300 and the charger 200 is that, the charger 300 further includes a frame 340. The frame 340 includes a bottom portion 342, a top portion 344 and an elastic portion 346, and has an accommodating space S3. The elastic portion 346 is connected between the bottom portion 342 and the top portion 344, and the accommodating space S3 is formed between the bottom portion 342 and the top portion 344. The base 310 is pivoted to the bottom portion 342 of the frame 340 and adapted to rotate in relative to the frame 340 to move the first clamping portion 322 into the accommodating space S3 as shown in FIG. 12, or move the second clamping portion 324 into the accommodating space S3 as shown in FIG. 13.
When the first clamping portion 322 is located in the accommodating space S3 and the top portion 344 of the frame 340 is pressed as shown in FIG. 14, the elastic portion 346 of the frame 340 generates elastic deformation and the top portion 344 pushes the first clamping portion 322 to drive the clamping component 320 to rotate. In this case, a distance between the second clamping portion 324 and the second charging portion 314 is increased, such that the user may place the electronic device (not illustrated) between the second clamping portion 324 and the second charging portion 314. Similarly, when the second clamping portion 324 is located in the accommodating space S3 and the top portion 344 of the frame 340 is pressed as shown in FIG. 15, the elastic portion 346 of the frame 340 generates elastic deformation and pushes the second clamping portion 324 to drive the clamping component 320 to rotate. In this case, a distance between the first clamping portion 322 and the first charging portion 312 is increased, such that the user may place the electronic device (not illustrated) between the first clamping portion 322 and the first charging portion 312.
In summary, in the charger of the invention, the base further includes the second charging portion in addition to the first charging portion, so that one single charger is capable of charging different types of the electronic devices and the accessories thereof respectively through the first charging portion and the second charging portion. Accordingly, amount of the chargers may be reduced, so that it is convenient in storing or carrying the chargers for the user, and the problem of confusion in using multiple chargers may also be solved. In addition, the clamping component is designed to act with respect to the base to change the distance between the clamping portion and the charging portion, so that the user may place the electronic device between the clamping portion and the charging portion, so that the operations of the charger may be easier.
